论文摘要
将新标量腐烂到具有多个光子和夸克的最终状态,可能会导致高能量墙面的独特实验特征。如果标量得到高度提高,那么此类信号将更加引人注目,就像从更重的共振的衰减中产生的那样。我们在最小隐身玻色子模型的框架内研究了这种类型的事件,这是一种无异常的$ \ text {u}(1)_ {y'} $带有两个复杂标量式单元的标准模型扩展。结果表明,尽管这些信号可能具有横截面,但可以通过LHC运行2个数据使它们可观察到它们,但它们的实验覆盖率很小。我们还与观察到的CMS多余的联系建立了联系,以搜索新的标量腐烂到96 GEV附近的Diphoton最终状态。特别是,我们得出的结论是,预测的多光子特征与如此多余的特征兼容。
Cascade decays of new scalars into final states with multiple photons and possibly quarks may lead to distinctive experimental signatures at high-energy colliders. Such signals are even more striking if the scalars are highly boosted, as when produced from the decay of a much heavier resonance. We study this type of events within the framework of the minimal stealth boson model, an anomaly-free $\text{U}(1)_{Y'}$ extension of the Standard Model with two complex scalar singlets. It is shown that, while those signals may have cross sections that might render them observable with LHC Run 2 data, they have little experimental coverage. We also establish a connection with a CMS excess observed in searches for new scalars decaying into diphoton final states near 96 GeV. In particular, we conclude that the predicted multiphoton signatures are compatible with such excess.
